The Wood Rats are among the handsomest species of the Muride 
in North America. They are large in size, with a velvety fur, in 
some as soft as spun silk, with the upper parts mouse color, brown, 
or even a reddish hue, and white under parts, hands, and feet. One 
of the genera, NEoTOMA, presents the usual rat tail, scaly, long, and 
naked; but another, TEoNoma (north of United States and Mexican 
boundary), has a. tail similar to a squirrel’s, hairy, at times almost 
bushy, and the members of this genus are very handsome animals 
indeed. Being almost strictly nocturnal, the Wood Rat is not often 
seen by day, but as soon as darkness falls, if the cabin of the woods- 
man is near its haunts, it will be overrun with these animals, and 
they will be seen on floors and shelves and other parts of the home 
diligently seeking food. In such places they become very bold. 
climbing upon the bed and racing over the body of its sleeping oc- 
cupant. The naked-tailed species seems to have the majority of num- 
bers, but in appearance are excelled by the bushy-tailed. The sub- 
family has various genera, the members of which are more or less 
closely allied to each other, but none equal in size and general ap- 
pearance those of NEotoma and TEONOMA.
